Current Title

We can use onHeaderClick, onHeaderRightClick or onHeaderDoubleClick to get the current header that user clicked. Here, we use onHeaderDoubleClick as an example.

1. we can get clicked header type by

HeaderMouseEvent.getType();

2. we can get the header title by

public void onHeaderDoubleClick$spreadsheet(HeaderMouseEvent event) {
	String currentTitle = null;
	int headerType = event.getType();
	if (headerType == HeaderEvent.TOP_HEADER) {
		currentTitle = spreadsheet.getColumntitle(currentIndex);
	} else {
		currentTitle =  spreadsheet.getRowtitle(currentIndex);
	}
...

3. Then, set the current header title to textbox and open the popup.

Popup inputTitlePopup;
Textbox titleEditor;

public void onHeaderDoubleClick$spreadsheet(HeaderMouseEvent event) {
...
	inputTitlePopup.open(event.getPageX(), event.getPageY());
	titleEditor.setText(currentTitle);
	titleEditor.focus();
}

Edit Title

We can change the column title when the user clicks Enter

public void onOK$titleEditor() {
	HashMap<Integer, String> titles = new HashMap<Integer, String>();
	titles.put(Integer.valueOf(currentIndex), titleEditor.getText());
	
	if (isColumnHeader) {
		spreadsheet.setColumntitles(titles);
	} else {
		spreadsheet.setRowtitles(titles);
	}
	inputTitlePopup.close();
}
